Binhole
An airplane passenger who invades the bin space above your seat by: 1) Cramming the bin so full that your stuff won't fit; or 2) Boarding the plane earlier than their boarding group so they can perform #1 above; or 3) Placing their stuff in your bin despite the fact that their seat is nowhere near yours.
Oh, man, I gotta check my carry on. It won't fit because some binhole with two carry on bags took up all my space.
